Photovoltaic panel installation design and construction specifications

These specifications were created with certain assumptions about the house and the proposed solar energy system. They are designed for builders. . Builders should use EPA’s online RERH SSAT to demonstrate that each proposed system site location meets a minimum solar resource potential. EPA has developed an online site. . EPA has developed the following RERH specification as an educational resource for interested builders. EPA does not conduct third-party verification of the site data or the online site. . The builder should install a 1” metal conduit from the designated inverter location to the main service panel where the system is intended to be tied into the home’s electrical service.. [pdf]
